Because darker surfaces need more light because it's a dark surface
A dark surface will absorb the heat from sunlight. While a white surface will reflect a lot of the sunlight and remain cooler.
Technically, White is not a color ... However, white and light coloured surfaces tend to reflect light while black and dark coloured surfaces tend to absorb light.
They are phosphorescent. Flourescent means light reflective, phos means light absorbing. They absorb light and retain it till it it has depleted.
Dark, rough, and/or porous surfaces absorb the most heat (ex. Asphalt)
Dark matt surfaces absorb radiated heat much more easily than light-coloured shiny surfaces.
"dark" implies that the object does not reflect light very well - thus it must be absorbing radiation.
Dark colours don not actually attract heat they absorb it where the lighter the colour the more reflective it is
White or light coloured surfaces, of which a cloud is an example, reflects sunlight, while dark surfaces absorb sunlight and heats up.
Dark colored cars absorb more heat from the sun because they are refractive rather than reflective. That is to say, dark colors - on a car or anything else - absorb heat, rather than reflecting it back the way light colors and white do.
Dark colors absorb heat from light better.
A reflector is a, usually large, sheet of reflective material to reflect light into shadows of an object. Materials such as metals reflect light, whilst materials such as wood and paper do not.
Dark colors absorb light creating thermal energy. Light colors reflect more light and heat away.
